RIP, swan photo, since deleted from all social media accounts.taylorswift/InstagramAll is apparently not fine between exes Taylor Swift and Calvin Harris.

Fans have been following along with the couple since they split in June. What first started out amicably transformed to shady comments and deleted social media posts. For her part, Swift has been fairly mum about the whole thing and is currently traveling the world with her new alleged beau, Tom Hiddleston.

And aside from a few posts earlier in the summer, everything seemed to be okay, but a series of tweets posted by Harris Wednesday afternoon has sparked a new discussion about the ex's relationship.

For those needing a refresher on the Swift/Harris relationship, here's a rundown of the timeline:

The couple began dating in March 2015.

According to E! Online, the two met in February thanks to an introduction by Ellie Goulding. They met again a day later at the Brit Awards and officially began dating March 6, 2015, as revealed by a one-year anniversary post they would share in 2016.

During their romantic year together, the couple shared numerous photos to social media accounts that they have since deleted, including group dates, award show congrats, and vacation pics.

The couple celebrated their one-year anniversary, March 6, as revealed by a post shared on Instagram. Harris had gotten her a locket engraved with the date they started dating.

In her April Vogue cover story, Swift said, "I'm just taking things as they come. I'm in a magical relationship right now. And of course I want it to be ours, and low-key…this is the one thing that's been mine about my personal life."

Calvin Harris released "This Is What You Came For" with Rihanna in April.

In April 2016, Harris and Rihanna performed at Coachella, and that's where he introduced "This Is What You Came For" to Rihanna.

Swift was in attendance and wore a jacket with an image that would later be revealed to be a promotion of Harris and Rihanna's new song.

On April 26, "This Is What You Came For" got its official release.

Following the release of the new hit song, Harris did an interview with Ryan Seacrest in which the host asked him if he would ever do a song with Swift.

"You know we haven't even spoken about it," Harris said. "I can't see it happening though."

After those photos emerged, it was revealed that Harris deleted his kind breakup tweet and unfollowed her on social media. He then blocked some of her fans. Shortly thereafter, Swift began to delete all signs of him from her social media.

In June, Harris posted a series of Snapchats showing that he was apparently doing fine after the breakup.

Calvin Harris seemed to be doing just fine. Snapchat/Calvin Harris But then Instagram comments allegedly written by him seemed slightly bitter.

"And she sings on a little bit of it too," he wrote in a tweet. "Amazing lyric writer and she smashed it as usual."

He also said that it was Swift who wanted to keep her involvement a secret.

That started out nicely enough, but then Harris swung the hammer: "Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though," he wrote. "I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do."

As if referencing her new relationship wasn't enough, he also mentioned her alleged long-standing feud with Katy Perry — possibly the first sort of confirmation from someone associated with Swift that the feud is, indeed, real.

"I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it," he wrote. "Please focus on the positive aspects of YOUR life because you've earned a great one." It was Harris' earlier denial of a collaboration that is rumored to have led to the breakup, according to TMZ.

So was the song the source of the split? We may never know, but they each have their own lives to live.

Swift is gallivanting around the world and making fan's dreams come true with surprise visits to hospitals, and Harris is basking in the success of his hit song. They'll both be fine.
